Dysautonomia refers to a group of conditions involving dysregulation of the autonomic nervous system, which controls automatic functions such as heart rate, blood pressure, and circulation.
One recognised form is Postural Orthostatic Tachycardia Syndrome, commonly known as POTS or POTS syndrome. In POTS, heart rate increases excessively when moving from lying down to standing, without a significant drop in blood pressure. This exaggerated response can lead to symptoms that affect daily life but are not usually associated with structural heart disease.
POTS and other forms of dysautonomia are physiological conditions involving altered regulation of circulation. Symptoms are real and often fluctuate over time. They are not a primary structural heart disease and are not caused solely by anxiety, although anxiety may coexist as it can with many chronic conditions. Periods of improvement and flare are common and do not indicate damage or treatment failure.
People with POTS may experience:
Symptoms can vary in intensity and frequency. While POTS symptoms may significantly affect quality of life, they do not typically indicate permanent heart damage.
Assessment begins with careful clinical history and examination. The aim is to determine whether POTS syndrome or another form of dysautonomia is present and to exclude alternative explanations for symptoms.
Diagnosis is based on recognised criteria, including an excessive increase in heart rate on standing in the absence of a significant blood pressure drop, together with compatible symptoms. Investigations may include heart rhythm assessment, blood pressure monitoring, or other targeted tests. These are guided by clinical context rather than performed routinely.
Testing is undertaken to provide clarity. A clear explanation of findings is central to care, as understanding the condition often reduces uncertainty and supports more confident decision-making.
Management of dysautonomia and POTS is structured and individualised. There is no single approach that suits everyone, and treatment plans are adapted to symptoms, lifestyle, and tolerance.
Care may focus on:
Improvement is often gradual rather than immediate. Many people experience meaningful functional gains over time with consistent guidance. The aim of management is to reduce symptom burden, improve day-to-day function, support return to work or study, and avoid unnecessary medicalisation. The focus remains on restoring capacity rather than reinforcing illness identity.
